Year 2026 Guidance
NEW YORK, April 1, 2026 – Shake
Shack Inc. (“Shake Shack” or the “Company”) (NYSE: SHAK) today announced Project Catalyst, a comprehensive technology
initiative to scale its digital, data, and operational platforms as the Company expands to 1,500 Company-operated Shacks.
Grounded in Shake Shack’s commitment to
Enlightened Hospitality, Project Catalyst focuses on modernizing restaurant systems, launching the brand’s first loyalty platform,
expanding AI capabilities, and advancing its data foundation to improve operational efficiency, deepen guest engagement, and unlock enterprise
productivity.
“Shake Shack
is entering a significant phase of growth and building the right foundation to support that scale
is a top priority,” said Rob Lynch, Chief Executive Officer of Shake Shack. “Project Catalyst
strengthens the technology and digital capabilities that power our restaurants and connect us more meaningfully with our guests. These
investments will help our teams operate more efficiently, enhance the guest experience, and position Shake Shack to scale successfully
toward 1,500 Company-operated Shacks.”
Key Elements of Project Catalyst
Modern POS and Kitchen Display Systems
Shake Shack has engaged Qu, a cloud-native unified
commerce platform built for fast-growing restaurant brands, to evolve its POS and Kitchen Display Systems and improve throughput, accuracy,
and operational execution. Enhanced kitchen orchestration and seamless ordering across digital and in-Shack channels streamline operations
and elevate consistency across every guest interaction. Qu’s proprietary in-store cloud and edge computing solution, Qube®,
enables faster, more precise service, particularly during peak demand, while empowering team members to stay focused on delivering Shake
Shack’s signature hospitality.
Shake Shack’s First Loyalty Platform
Shake Shack is developing its first loyalty platform,
a modern guest engagement solution designed to strengthen guest relationships, drive frequency, and reach new guests looking for enhanced
experiences and hospitality.
The platform will integrate across POS and digital
channels to enable more personalized communication and experiences, allowing Shake Shack to advance its promotional strategy toward deeper
engagement that drives retention, frequency, and long-term guest value.
Expanded AI Capabilities
Shake Shack is bringing to life a new generation
of proprietary AI capabilities to enhance restaurant operations, elevate guest engagement, and drive enterprise productivity, with significantly
more innovation planned over time.
These capabilities are focused on delivering
real-time operational insights, enabling faster and more informed decision-making, and providing intelligent support to restaurant operators
and support teams. By embedding AI into daily workflows, Shake Shack is enabling teams to better understand performance, identify opportunities,
and act with greater speed and precision.
At the center of this vision is an intelligent
operating layer for every Shack, surfacing proactive insights, alerts, and recommendations that help operators run great restaurants every
day.
Together, these capabilities form the foundation
of Shake Shack’s AI roadmap, with continued expansion planned to unlock new efficiencies, accelerate decision-making, and further
personalize the guest experience at scale.
Data & Insight Platforms
Project Catalyst advances Shake Shack’s
data foundation, enabling faster, more consistent access to actionable insights across the business.
By bringing together operational data, guest
behavior, and advanced analytics, Shake Shack is creating a unified view of performance that supports better decision-making at every
level of the organization. These capabilities will enable more personalized guest experiences, improved service speed and accuracy, and
stronger operational execution across the system.
This foundation will also serve as the backbone
for Shake Shack’s expanding AI capabilities, with continued investment to unlock deeper insights, automation, and scale.
“As Shake Shack continues to grow, we’re
building a technology platform designed to scale with the business,” said Justin Mennen, Chief Information and Technology Officer
of Shake Shack. “Project Catalyst brings together modern restaurant systems, advanced data platforms, and AI-driven capabilities
that help our teams operate more efficiently and make faster decisions. By connecting our POS, digital, loyalty, and AI capabilities into
one ecosystem, we’re creating the foundation to deliver Enlightened Hospitality at scale.”

In conjunction with this announcement, the Company
is reiterating its First Quarter and Fiscal Year 2026 guidance along with its Three-Year Financial Targets provided in its Q4 2025
Shake Shack Shareholder Letter. The Company’s stated guidance incorporates the planned impacts and encompassing technology
initiatives associated with Project Catalyst.
